What are the other industry standards for testing colorfastness?

Color fastness testing is the process of evaluating whether a fabric or dye will fade or bleed under washing, rubbing, exposure, and other conditions. The following are some commonly used industry standards and test methods:

1. AATCC TM61-2016: This is a standard test method issued by the American Association of Textile Chemical Technology (AATCC) to evaluate the color fastness of fabrics. The method covers Color fastness tests under conditions such as washing, rubbing, exposure and perspiration.

2. ISO 105: This is a series of standards issued by the International Organization for Standardization (ISO) to evaluate the color fastness of fabrics and dyes. ISO 105 includes multiple parts, such as ISO 105-C06 (washing Color fastness test), ISO 105-X12 (exposure Color fastness test) and ISO 105-D01 (rubbing Color fastness test) and so on.

3. ASTM D2054-08: This is a standard test method issued by the American Society for Testing and Materials (ASTM) to evaluate the color fastness of fabrics. The method covers Color fastness tests under conditions such as washing, rubbing and exposure.

4. GB/T 3921-2008: This is the standard issued by the National Standardization Administration of China to evaluate the color fastness of fabrics. The standard includes Color fastness tests under conditions such as washing, rubbing, exposure, and acid-base conditions.

These standard test methods typically involve exposing fabric samples to specific conditions, such as washing solutions, acid-base solutions, exposure equipment, or rubbing devices, and evaluating color fastness by comparing the color change before and after the sample. Test results are usually expressed as a numerical grade or degree of color change.

It should be noted that different fabric types, dyeing methods and washing conditions may have an impact on the test results. Therefore, when conducting the Color fastness test, specific test methods should be followed, and actual use conditions and fabric characteristics should be taken into consideration. Also, refer to the care instructions provided by the fabric or garment manufacturer and use detergents and care methods appropriate for the specific material.
